:MEASure:DMeasure[:SIGMA]
Syntax Sets the delta computation mode for wiring unit
ΣA or queries the current setting.
Syntax :MEASure:DMeasure[:SIGMA] {OFF|
DIFFerence|P3W3_V3A3|ST_DT|DT_ST}
:MEASure:DMeasure:SIGMA?
Example :MEASURE:DMEASURE:SIGMA OFF
:MEASURE:DMEASURE:SIGMA? ->
:MEASURE:DMEASURE:SIGMA OFF
Description • This command is valid only on models with
the delta computation function (/DT option).
• The selections are as shown below: The
wiring system of wiring unit ΣA determines the
selectable modes.
OFF = No delta computation (single-phase,
two-wire system (1P2W) only)
DIFFerence = Differential voltage, differential
current (single-phase, three-wire system
(1P3W), three-phase, three-wire system
(3P3W) only)
P3W3_V3A3 = 3P3W-to-3V3A conversion
(single-phase, three-wire system (1P3W),
three-phase, three-wire system (3P3W) only)
ST_DT = Star-to-Delta conversion (three-
phase, four-wire system (3P4W) only)
DT_ST = Delta->Star conversion (three-
phase, three-wire (three-voltage, three
current) system [3P3W (3V3A)] only)
:MEASure:DMeasure:SIGMB
Syntax Sets the delta computation mode for wiring unit
ΣB or queries the current setting.
Syntax :MEASure:DMeasure:SIGMB {OFF|
DIFFerence|P3W3_V3A3|ST_DT|DT_ST}
:MEASure:DMeasure:SIGMB?
Example :MEASURE:DMEASURE:SIGMB OFF
:MEASURE:DMEASURE:SIGMB? ->
:MEASURE:DMEASURE:SIGMB OFF
Description • This command is valid only on 4-element
models with the delta computation function (/
DT option).
• The selections are the same as the
":MEASure:DMeasure[:SIGMA]"
command. The wiring system of wiring unit
ΣB determines the selectable modes.
:MEASure:EFFiciency?
Function Queries all settings related to the efficiency
computation.
Syntax :MEASure:EFFiciency?
Example :MEASURE:EFFICIENCY? ->
:MEASURE:EFFICIENCY:ETA1 PB,PA;
ETA2 PA,PB;ETA3 OFF;ETA4 OFF;
UDEF1 P1;UDEF2 P1
6-78
:MEASure:EFFiciency:ETA<x>
Function Sets the efficiency equation or queries the
current setting.
Syntax :MEASure:EFFiciency:ETA<x> {(OFF|
P<x>|PA|PB|PM|UDEF<x>)[,(P<x>|PA|
PB|PM|UDEF<x>)]}
:MEASure:EFFiciency:ETA<x>?
<x> of ETA<x> = 1 to 4 (η1 to η4)
OFF = No computation (the denominator is
ignored)
<x> of P<x> = 1 to 4 (element)
PA = PΣA (only on models with 2 to 4 elements)
PB = PΣB (only on models with 4 elements)
PM = Pm (motor output, motor version (-MV)
only)
<x> of UDEF<x> = 1 to 2 (Udef1 to Udef2)
Example :MEASURE:EFFICIENCY:ETA1 PB,PA
:MEASURE:EFFICIENCY:ETA1? ->
:MEASURE:EFFICIENCY:ETA1 PB,PA
Description • Set the numerator and then the denominator.
• The numerator can be omitted. The
numerator is set to 1 when omitted.
• The numerator is omitted when the numerator
is 1 in the response to a query.
:MEASure:EFFiciency:UDEF<x>
Function Sets the user-defined parameter used in the
efficiency equation or queries the current
setting.
Syntax :MEASure:EFFiciency:UDEF<x> {(NONE|
P<x>|PA|PB|PM)[,(NONE|P<x>|PA|PB|
PM)][,(NONE|P<x>|PA|PB|PM)][,(NONE|
P<x>|PA|PB|PM)]}
:MEASure:EFFiciency:UDEF<x>?
<x> of UDEF<x> = 1 to 2 (Udef1 to Udef2)
NONE = No parameters
<x> of P<x> = 1 to 4 (element)
PA = PΣA (only on models with 2 to 4 elements)
PB = PΣB (only on models with 4 elements)
PM = Pm (motor output, motor version (-MV)
only)
Example :MEASURE:EFFICIENCY:UDEF1 P1,P2,P3
:MEASURE:EFFICIENCY:UDEF1? ->
:MEASURE:EFFICIENCY:UDEF1 P1,P2,P3
Description • Set the parameters in the order parameter 1,
parameter 2, parameter 3, and parameter 4.
• Parameters 2 to 4 can be omitted. Omitted
parameters are set to NONE.
• Parameters are omitted when all of the
subsequent parameters are NONE for
parameters 2 to 4 in the response to a query.
